I'll wait and see
This kind of stuff existed on the N95 years ago, but never made much traction due to the lack of mobile devices that actually have GPS on them... if there's only a couple of hundred users in the UK it's not a lot of use.
I wait to see if it works this time. There's still the lack of hardware... cell tower triangulation is fairly useless as (at least in the UK) it only tells you what city you're in - and doesn't even get that right (Google maps thinks I live in the north sea).
Maybe with the iphone it'll hit critical mass and become useful. Worth keeping an eye on.
